Question
Write the slope of the line whose inclination is$: 45^\circ .$
✓
Answer
If $\theta $ is the inclination of a line; the slope of the line is $\tan \theta $ and is usually denoted by letter $m.$
Here the inclination of a line is $45^\circ ,$ then $\theta = 45^\circ $
Therefore the slope of the line is $m = \tan 45^\circ = 1$
Here the inclination of a line is $45^\circ ,$ then $\theta = 45^\circ $
Therefore the slope of the line is $m = \tan 45^\circ = 1$
